BMW 6-Series GC takes on the rivals

The days of the traditional boxy saloon are numbered. Meet the new breed of more-door supercoupe

That change also helped the ride. Help the A7 could very much do with. It clumps and thumps, and, worst of all in a big long-distance cruiser, kicks up a grinding squall of tyre noise on many A-road and motorway surfaces. The BMW does a usefully better job of rounding off most bumps, especially with the chassis in its Comfort setting (I drove like that, instead of Sport, on lumpy twisty roads too, as it makes the car feel more fluent). But, like the Audi, if to a lesser extent, there's a sharpness and noisiness underlying it. Also, the BMW can jostle side to side on a rural road. This doesn't affect your speed, but it's noticeable after the CLS. It's also more susceptible to motorway crosswinds than the CLS.
